The specific embodiment
See also Fig. 1 to Fig. 3, be the selected example structure of the present invention shown in the figure.
The dynamic torque tool of the comprehensive rotation of present embodiment, as shown in Figures 1 and 2, it is to comprise:
One hollow handle 1 has a shank part 11 free to rotate and the connecting portion 12 of a tool torsion visualizer 121;
One hollow axostyle 2, the one end is connected with this connecting portion 12, and these axostylus axostyle 2 inboards have one first bar 21 and one second bar 22, this first bar 21 has one first end 211 and one second end 212, first end 211 of this first bar 21 and second end 222 of second bar 22 are setting in opposite directions, first end 211 at this first bar 21 is arranged with one first groove 213, to establishing one second groove 223 at these second bar, 22 second ends 222 by first groove 213, to form the accommodation space 23 that assumes diamond in shape without exception, be placed in this accommodation space 23 for a tumbler 24.In the present embodiment, this tumbler 24 is meant a steel ball, this first bar 21 is with this second bar 22 shores shape, and this axostylus axostyle 2 is established a joint portion 25 away from an end of this connecting portion 12, and this joint portion 25 is arranged with an installing groove 251.In the present embodiment, this installing groove 251 is to be pyramidal, installs for a head 3, and establishes an annular groove 26 at these installing groove 251 rings, and is ccontaining for positioning piece 4.In the present embodiment, this keeper 4 is a C type clasp, to locate this head 3;
A rotation section 27 is established away from an end of head 3 and 212 at second end of this first bar 21 in this joint portion 25, and 2 of this joint portion 25 and axostylus axostyles can be produced relative rotation.In the present embodiment, this rotation section 27 is a cylinder, the two ends of this rotation section 27 connect second end 212 of this joint portion 25 and this first bar 21 respectively, and this 25 places, adjacent joint portion of rotation section 27 peripheries ring is established several holes 272, each hole 272 is to be provided with in the mode that enlarges gradually from inside to outside, plugs for more than one latch 28.
Because being first end 211 of this first bar 21 in a hollow axostyle 2, this dynamic torque tool is arranged with this first groove 213, to should first groove 213, be provided with this second groove 223 at these second bar, 22 second ends 222, be placed in these first, second groove 213,223 formed accommodation spaces 23 for a tumbler 24.Whereby, remove and can reduce the active force that this tumbler 24 is born, outside the service life of improving this dynamic torque tool, can also make this first bar 21 become a member free to rotate, making this dynamic torque tool is the instrument that a nothing is rotated the dead angle.
